SPEClFICATION forming vpart of Letters Patent No. 320,973, dated June 30, 1885.

Application filed February 7, 1885. (No model.)

Tol all whom it may concern:

Be it known that I, Louis S. SAYLoR, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Rolling Mill Hooking and Carrying Machines, of which the following is a specification.

In operating oldst-yle rolling-mills oneof the most laborious and lsevere parts of the [o work is that which has been known as hooking#that is, raising and lowering the blooms and partly-rolled rails as they are run through the rollsand much time and labor-have been spent to produce satisfactory machinery for .15 performing the work. This is the object of mypresent invention, and said invention principally consists in tables mounted on tracks running along parallel with the rolls, provided with rollers mounted on swinging arms, and 2O mechanism for driving said tables back and forth and raising and lowering said rollers.

It further consists in certain details of construction and arrangement of paris, as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a top or plan view of the rolls of a rolling-mill and the appliances and mechanism adjacent thereto, my invention being embodied therein; Fig. 2, a side elevation of the same, as seen from the dotted linezz in Fig. l; Fig. 3, a similar view to a portion of Fig. 1 on an enlarged scale; Fig. 4, a front ele- 3 5 vation of the mill, showing one table in transverse section, as seen from the dotted line yy; Fig. 5, a transverse vertical sectional view looking to the right from the dotted line @a x in Fig. 3; Fig. 6, atransverse vertical sectional 4o view looking toward the left from the dotted line 'w w in Fig. 3; Fig. 7, a similar view to Fig. 5, except it is shown as when looking to the left from the dotted line m a', with the rollers in the tables raised; Fig. 8, av detail perspective view of the mech-anism for driving the rollers in one, of the tables when said table is in a certain position; Fig. 9, a transverse sectional view through one of the eccentrics; Fig. 10, a longitudinal sectional view of the same and adjacent parts, and Fig. 11 ade'tail 5o vertical sectional view ofthe stop for one ofthe eccentric-shafts.

In said drawings the portions marked'A represent the foundation and framework to the mill; B, the roll-housing; C, the tracks upon which the tables are mounted; D E, said tables; F, a shaft bywhich, through rackbars or other-suitable connection, said tables `are drivenback and forth; G G2, shafts car- -ably arranged to support the roll-housings,

tracks, tables, and the various mechanisms for 7o operating the same, as will be readily understood, and not being peculiar except .in their adaptability tothe arrangement of mechanism illustrated, they will not be further described herein. l r

The roll-housings B, the roughing-rollsBf, and finishing-rolls B2, mounted therein, are or may be of the ordinary or any well-known form, and will be readily understood by an examination of the drawings.

The tracks O for the tables are arranged alongside, a suitable distance from, and parallel to the rolls upon bearings in the foundation or frame-work A, provided therefor. They support and guide the tables D and E as S 5 they move back and forth in front of the rolls. The top edges of said tracks, upon which the 4 tables directly rest, are ^shaped to fit into similarly-formed notches in the under side of` the frame-work of the tables, and said tables 9oy are thus held in exact position thereon.

The tables D and E, as before indicated, rest and move upon the track C, being preferably provided with small trucks c to facili-. tate this operation. They are driven by the shaft F through long rack-bars D and E', rigidly connected thereto, which engage with spur-pinions f on said shaft.

The table D is provided with a set of swing# ing arms, d, the lower ends of which are pivoted to the frame-work of the table, and are provided with bearings upon the upper ends in which rest the rollers D. These arms are connected together so that they will rise and fall in unison, carrying the rollers with them, and are operated through rods g by eccentrics g upon the shaft G", said shaft G being driven by the shaft G. This table'is also provided with guide sides D3, which are also mounted on the upper ends of the swinging. arms, and are thus operated to rise and fall with the rolls. Upon the ends ofthe shafts of the rollers D2 are placed miter gear-wheels d2, which are adapted, when the table reaches the position directlyin front of the roughing-rolls B, to engage with similar miter-gearsg' ,on the shaft J. At the same sime projecting arms d3 on the side of the table D engage wit-h the upper end of the lever D, drawing it to one side, which, through the connecting-rod d* and the clutch-lever J operates the clutch J 2 to engage with the loose miter-gear ji upon the end of the shaft J, which is constantly engaged with a similar miter gear, t', on the shaft I, and thus driven, said clutch J2 being prevented from rotating on the shaft J by a spline in the usual manner, while being permitted a free endwise movement thereon. By this arrangement, as will be readily seen, theshaft J is permitted to remain stationary at all times except when the table comes into the described position,when it is set in mot,ion,and the rollers in said table driven thereby, thus operating to carry the bloom or partly-rolled rail into the desired pass of the' rolls of the rolling-mill, and upon said table being moved away from said position the arms dBtheren operated to disengage the clutch and permit said shaft J to again become motionless.

The table E is operated generally in much the same manner as is the table D, being provided with a set of rising and falling arms, e, carrying rollers E2, which are operated in the same manner through rods g by cams g2 on the shaft G2, said shaft G2 being also driven by the shaft G. The sides E3 of this table correspond to the sides D3 of the table D, and may either be mounted and operated in the same manner, or may be simplyextensions of the sides of the table as the rollers of this table receive rails from the rolls 4only when in depressed position. .This table E has projecting portions upon its outer end carrying pins e,which are adapted to engage, as the table reaches the position behind the finishing-rolls, with a permanent table-section, E4, carrying rollers also mounted on pivoted swinging arms, and thus, as the rollers of this table are raised when in the stated position, the rollers of said permanent table-section are raised with them, and thus the length of this table is increased practically in this position to any desired extent.

The shaft F is arranged transversely to the rolls and extends across from one side to the other, and carries the pinions f, by which, through the rack-bars D and E', the tables D and E are driven. It is operated by a fric,- tion-clutch, F', between the two parts of which is a'suitable pinion on the end of the shaft F, running at right angles with said shaft F, said shaft F2 being driven from the operating-shaft H, its end carrying the pinion being adapted to be moved back and forth, so as to bring said pinion into contact with one or the other of the clutch parts by means of arod,f2, running to an operating-lever, F3. Thus, as will be readily seen by an examination of the drawings, especially Fig. 3,7by simply pushing or pulling on the lever F3 the shaft F can be .driven in one or the other direction, andthe tables D and 'E moved back and forth along the tracks. I

The shaft G runs parallel with the shaft F, and through suitable gears drives the shafts G and G2, carrying the eccentrics g and g2, by which the rollers in the tables are lifted or depressed. Two loose pulleys, g and g, upon said shaft are driven in opposite directions by a suitable arrangement of belts, as shown, and between them upon the shaft is a doublefaced. clutch, which is prevented inthe usual manner from revolving loosely on the shaft by means of a spline, and which may be operated by a lever, g5, to engage with a clutchface upon either of said pulleys. A connecting-rod, g, runs from said lever to an operating-lever, g4, situated near the lever F3, and by means of which said clutch can be thrown into or out of engagement with either of said pulleys g3 or g, and the shaft G thus driven in either direction. Thus the same operator that handles the lever F3 can by similarly operating the lever G4 revolve the shafts G and G2 and raise or lower the rollers in the tables. The eccentrics g g'l are mounted between downwardly-projecting portions on the frame-work of the tables, as shown most plainly in Fig. 10, and are thus carried back and forth along the shafts with said tables, being loosely mounted so as to permit this operation. They are prevented from turning, however` bylong splines in said shafts, which are shown most plainly in Figs. 9 and 10. Upon the ends of said shafts G' and G2 which are farthest from the shaft G are placed arms gl, which are adapted, when the rolls have been raised to the utmost height and the eccentrics have just passed the center, to come in contact with and be supported by suitable stops, A', said stops being arranged in suitable position on the foundation or frame work, and being preferably spring-stops, as shown in Fig. l1, in order to prevent a too violent concussion as the arms strike them.

The shaft H is an ordinary 'drivingshaft, and receives its motion either from the rollshaft or from the engine, or any other suitable source, and is connected by suitable gears and belts with the shafts F and G, thus imparting motion thereto.

IOO

IIO

AThe shaft I' is a stationary shaft, carryingv ordinary ydriving-rolls arranged in front of the rolls of the mill, and, like the shaft H, is driven from any suitable or desired source.

rlhe operation offmy said invent-ion may be recapitulated as follows: The rolls and the driving-shaft H being in motion, and the tables in the position shown most plainly by the full lines in Fig. 3 and in Figs. 5 and 6, the bloom as iteomes from the tracks is run onto the table D, and the rollers of said table being in motion'they carry it forward toward the rolls', being assisted during the latter part of this operation by the feedroll l'on the shaft I. Upon leaving the rolls the now partly-rolled rail comes onto thetable E, when the operator, standing by the levers F3 and G, pushes upon the lever G4, throwing the clutch G3 into en gagement with the pulley g3, thus setting the shaft G in motion, and, through the shafts G' and G2, the eccentries thereon, the connectingrods g, and the swinging arms on the tables, raising the rollers in said tables up to aheight level with the upper passes in the rolls. As soon as the partly-rolled rail is received on the table E and said table has been raised the operator pushes upon the lever F3, throwing the friction-clutch on the shaft F into engagement, and thus moving the tables somewhat along the tracks, bringing the partly-rolled rail in front of the next pass. The operator, standing near the table E, then starts the partly rolled rail back through said pass, whence it is delivered again to the table D.

The operator, standing near the levers, then pulls upon the lever G4, throwing the clutch G3 into engagement with the pulley g, which revolves the shafts G, G', and G2 in the opposite direction, lowering the rolls to their former level. The partly rolled rail is then pushed onto the next lower pass, and this operation is continued until the rail is finished. When the rail reaches the last pass of the finishing-roll, it being by this time of considerable length, and needinga longer support than the table itself, the table E couples onto the table-section E4, as before described, and raises the rolls thereof as though said sect-ion were a part of itself. Thus it will be seen that by the use of my invention a single operator by proper manipulation of levers is enabled to raise and lower the blooms or partly-rolled rails, as may be desired, and to move them from one position to another in relation tothe rolls as may be necessary to bring them inline with the proper pass.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-
